TIN-PLATE cn'ronnie.

Specification of Letters Patent.

Patented Nov. 26, 1918.

I '0 all whom it may concern:

Be it known that I, GEORGE L. ALLEN, a citizen of the United States ofAmerica, residing at 'Warren, in the county of Trum bull and State ofOhio, have invented certain new and useful Improvements in Tin- PlateCatchers, of which the following is a specification.

My invention relates to improvements in plate catchers suchas areordinarily located on top of tinning pots in the manufacture of tinplates, and which can be used also for all like operations; and theobjects of my invention are, first, to provide catchers which willreceive the plates when pushed up from the tin pots and deliver them toa receiving and cooling table in perfectly fiat and even conditionwithout warped edges or central waves or bends, and of uniformthickness; and, second, to reduce the cost by eliminating Waste and lossdue to the production of uneven and imperfect plates called culls.

I accomplish those objects by the mechanism described, illustrated inthe accompanying drawings and clearly pointed out in the claims.

In Figure 1, I show a conventional tin pot, in section, with myinvention located on top thereof, in elevation.

In Fig. 2 I show my invention in perspective.

Like characters refer to similar parts throughout the several views inwhich P, represents a tin pot of any form, and in present practice .hasa flux boX E, into which plates which are to be tinned are passed, andwhich comprises top and bottom aprons A, A, to guide the plates throughmolten tin T, up and between receiving rolls R, It, which rolls lie inoil floating on said tin and are operated by external mechanism, (notshown) so as to pass the plates up and out of the top of the tin pot P,where they are caught by the rollers 1, 1' and 2, 2, of my invention.

My rollers 1, 2, etc., consist of a plurality of pairs, operated asfollows 2- A desirable number of rollers 1, 1, are rigidly attached to ashaft 3 which is rotated in any way, as by a belt over a driving pulley4, and riding in bearings 5 in a supporting frame F, which is bolted orotherwise attached to the top of the tin pot, P.

As illustrated, a second rotating shaft 6 is supported by bearings 8, 8,attached to the frame F, and has a gear wheel 7 on one of its ends,which meshes with an idler gear wheel 9 sustained by the frame F, whichgear 9 in turn meshes with a gear 10 rigidly attached to shaft 3.Consequently rotation of the pulley 4 rotates gears 10, 9 and 7 andshaft 6.

In the form of my invention illustrated, an inverted T-bar 11 is shownas bolted to the ends of frame F and parallel to the shafts 3 and 6. Anybar or equivalent sup port may be used.

To the under side of said T-bar 11, are fastened rigidly a plurality ofhangers 12, 12 onsisting of a top and two parallel legs 13, 18, throughholes in each of which the shaft 6 revolves.

Inside of said legs 13, 13' thereto are corresponding arms 14, 14 of aplurality of roller-carrying rockers 15, 15, having the rolls 2, 2journaled therein between the tops of said arms 14, 14.

Springs S. S are connected to the adjacent faces of the rockers 15, 15and the T-bar 11.

In line with rolls 1, 1, are the corresponding rolls 2, 2, each of whichhas an annular ring chamfered therein with gear teeth 16, 16 cut intothe surface thereof.

Said teeth 16, 16 mesh with the teeth of gears 17, 17 rigidly attachedto shaft 6.

In practice the tinned plates having passed up out of the tin-pot arecaught between the rolls 1, 2 and 1, 2, which serve to lift them out androll them on to a receiving table (not shown). The resiliency of thesprings S, S, normally holds the rollers 1 and 2 and 1 and 2 together,respectively, but in instances of the passing through of plates ofslightly varying and parallel thicknesses, or of warped contour, myrolls yielding, allow passage thereof by compression of the springs S,and in consequence do not squeeze, warp, wrinkle nor press the platesout of shape'nor change the straight edges of their evenly cut sides andends.

I claim:

1. In a plate catcher of the kind described, a plurality of rollerslocated in independently and resiliently contacting pairs above themetal pot and sustained by a frameattached to said pot and actuated by atrain ofgears, asshown and described.

2. A plate catcher having .a .plurality of gripping rollers on a singlerotating shaft, and a plurality of cooperating gripping rollers eachindependently and revolubly mounted in a resilientrocker supported by ahanger, and actuated by gears, as shown and described.

3; A roller. for aaplate catching machine, having an annular channel inits periphery, and gear teeth therein below the level of itscircumference.

4. A roller for a plate catcher, having gear 'teeth countersunk belowits periphery and meshing with driving gears; a rockable support for theaxle endsof said rollers; a

driving gear and a compression spring normally retaining said roller incontact with a cooperating roller on a non-yielding shaft.

5. In a plate catcher, a plurality of driven catcher rollers arranged inpairs, one rollero'f each pair revolving on a nonyielding shaft, and itscorresponding roller revolving on an axle supported by a re ture in thepresence of two Witnesses.
